Freshwater macroinvertebrate family abundances in spring and autumn, England, 2002-2019
This data file contains processed data derived from the Environment Agency's Ecology and Fish Explorer Macroinvertebrate database. The recorded data is the abundance of freshwater macroinvertebrates taken by the Environment Agency (EA). The data were collected from sites throughout England, between 2002-2019, from March to May, and September to November. Samples were collected using three-minute kick-samples, whereby a net is used to catch invertebrates and debris flowing downstream of an area in a river which is disturbed by a recorder for three minutes. Data before 2002 were excluded as abundance of macroinvertebrates was not recorded widely before this year. The data were originally collected for the purpose of understanding water quality by the Environment Agency. The original EA data contains raw counts of mixed-taxonomic groupings of invertebrates and some diatoms and other taxa, from rivers in England with multiple sampling methodologies. Here, the derived data has been processed in such a way to combine counts at a single taxonomic level (family) containing only taxonomic groups of interest for the research, and the data are limited to one sampling method.

This data has been processed in the following manner: * Data from all EA sampling regions (Anglian, Midlands, Northeast, Northwest, Southern, Southwest and Thames) have been combined into one data file * Samples taken outside of the Spring (March-May inclusive) and Autumn (September-November inclusive) were removed * Data were restricted to three-minute kick samples only (meaning 'dredge' samples were removed) * All data taken before 2002 were removed * Only data classified in the following taxa by the EA were retained: Ephemeroptera, Plecoptera, Hemiptera, Megaloptera, Odonata, Coleoptera, Trichoptera, Turbellaria, Annelida, Crustacea, Diptera and Mollusca * Total abundance of macroinvertebrates per Sample ID were summed at the family-level within these taxa * Eleven samples with anomalous abundance counts for a taxonomic group were removed from the data * The number of sampling occurrences was calculated for each site-season-year combination, and only sites where samples had been taken in both spring and autumn at least once for a minimum of three years in the remaining time series (2002-2019) were retained. The data have been pooled by family and wider taxonomic groupings.
